The system concludes gasification scrubbing system the opposed multi-burner gasifier （OMB） methanol production and purification shift system. The distributions of ammonia con- centration in streams were obtained. The study demonstrates that ammonium crystallization problem caused by ammonia ac- cumulation, and if the process has ammonia exports its concentration will greatly reduced and the ammonia salt problem will effectively alleviate. Aspen plus simulation is a useful tool strengthening the ammonia recycling use and reducing pollutant for improving water quality, maintaining stable production, emissions.展开更多

This paper analysed the production process of the agro industrial cooperative producers of macadamia nut （Coopmac）, located in the town of Sao Mateus-ES/Brazil, and responsible for the production and marketing benefits for the states of Espirito Santo and Bahia. This analysis was performed in order to identify new opportunities for developing new products. The following steps were explored： analysis of the current procedure, ideas generation, analysis of potential ideas, development of a product concept and development of a prototype product. In cooperative, macadamia oil was only extracted. It was decided to develop a potential product from this oil. Initially, chemical analyzes were performed with this oil and opted for the production of soaps, liquid and bar. During this step, the methodology of design of experiments was used to develop the prototype. Sensory analysis, based on the LAM type hedonic scale, was used in the tests. The data were analyzed and could be distinguished the best formulation and the main effects for each assessed parameter. In this step, the statistical analysis software was used. From the value of the overall quality of the sample, greater acceptance for liquid soaps was obtained for a formulation with lower oil volume and higher volume of amphoteric. When concerning the sample bar soaps, the best formulation had the lower ratio of oil volume, the higher volume of amphoteric and lower mass of clay. The authors expect to contribute to generation of scientific and technological knowledge in order to effectively meet the practical needs of efforts directed to the production of macadamia nuts in the state of Espirito Santo.展开更多
